2007 Bentley Continental GT Aftermarket Bluetooth head unit

[chrisf-1]

Hi again everyone I have just bought the above car which does not seem to be Bluetooth connectable to my Samsung S21 mobile phone, it has the usual sat-nav, CD player and also a phone in the armrest from the stone age, I have been advised to either buy a piece of equipment called "The Grom" which apparently is a Bluetooth add on that will enable my existing equipment to function with the standard OEM kit installed or change the head unit for an aftermarket one with Bluetooth installed, I just want to be able to use my phone hands free without doing any major surgery at a reasonable price, I am pretty much in the dark with all this so if anyone is available to sort this out for me at a reasonable price please let me know also any other advice on the easiest and straightforward way to go about this would be very helpful, I am located in Medway Kent UK Many thanks Chris
